Seismic Performance Evaluation of Seesaw Braced Energy Dissipation System
A large amount of energy is dissipated to the structure during a major earthquake causing structural damage to the building. Based on the understanding about seismic activities, the need for seismic energy dissipation has become an important factor in structural engineering. A new vibration system based on seesaw mechanism characteristics and pretension effect is the seesaw energy dissipation system. The system comprises braces, seesaw members, and dampers. The frame moves right and left under a lateral load, and the tensile force generated in the braces is delivered to the seesaw member and the dampers dissipate the energy. As the tensile force occurs in bracing members, the issue of brace buckling problem can be avoided, such that it enables the use of steel rods for bracing members. Long steel rods can be used as bracing between the seesaw members and the moment frame connections, by introducing pretension in rods. This study focuses on the analysis of the seismic performance of the seesaw braced steel structure using different bracing configurations in different seismic zones as per IS code using the SAP 2000. This type of vibration control device provides an alternate solution for typical low rise steel frames with substantial damping and seismic response reduction.
